MPROVEMENT IN LAMP-BURNERS.

@the .tlphulr referat tu in time Enters. ttmt mit mating mi nf the smut.

TO -ALL WHOMI IT CON CERN Beit'knewn' that I, JOHN MAGEE, of Chelsea, inthe county of Suffolk, and State of- Massachusetts, have inventedcertain Improvements in Lamp-Burners, of which the-following is a full,clear, and exact description, reference being had to the accompanyingdrawings, making part of this specication, in which I Figure 1 is a planof the upper side of a'lamp-hurner, with my improvements appliedthereto.

Figure 2 is an elevation 'of the same.

Figures 3 and 4 are elevations of two p'ortions of the burner detached.

Figure 5 is a'section on the line :c w of ignQ.

The Vobject of" myinvention i's to provide a chimney-support or holder,which, together with the chimney Y secured thereonpmay be readilyremoved'at all times fromthe lamp without fear of burning the fingers,and

my invention consists in-a burner provided with a stationary cone, overthe top of which, and a langeor guide atits base, a perforatedchimneyhelderlmay be instantly fitted, without requiring any care inadjusting it thereon. Y A

To enable othersskilled in thc art to understand and use my invention,`Iu'ill proceed to describe the manner in which I lhave carried it out.A, v

In the said drawings, Arepresents the burner, the base of which isprovided in the ordinary manner with a screw-thread, a, which :tits-intothe screw-cap. of the lamp. Secured to or forming a part of the burner,`A, is astationary cone, B, (Hg. 3,) into which and through thev bottomof the burner passes a central Wick-tube, C. At thc base ofi thestationary cone is formed a circular flange, l), of' a diameterllargerthan the 'upper portion or body c of the cone, andlof the same diameteras the under side of the burner, which is provided with perfo- Vrationsel, through' which a current ot` air is admitted to `the`chambcr D,formed between the outside of Vthe wick-tube and inside ofthe cone, forinsuring perfect-combustion.

yE` is a, chimney-support, or holder, ofl the form'seen'inl fig. 4, theupper portion of which is provided with a circular opening', to allow ofits being: readily iitted upon the outside of the upper portion of thecone, the

surfaceof the parts in contact being slightly conical, and .carefullymade to lit eachother snugly.) The 'lower .portion of ythechimney-holderE consists of a Wide, circular Vperforated band, e, whichexactly lits over the outer edgey of the circular ange at the Abase ofthe cone, by which construction the holder may not only be instantlyguided .overthc top ofvthe cone, but may be pressed vdown snugly overthe flange b at its base, soA as to be securely heldin place thereon,the cenicalvsurfaces of the upper part of the coneand holder, when incontact, causing suilicient friction to Wedge't'hem together. I

The. cone is provided with twov apertures ff through its Side, the twoapertures being diametrically opposite, asv shown in g. 5. Between theperforated band e and the corre'` B is formed a chamber, in whichcirculates va. current of air, which is admitted .through theperforations inthe band e, (thereby cooling it,.) and passes lthroughthe apertures ff in the conc, whereit unites with'the current passingupthrough the pcrforations al, .in thcbottom of the burner, thus creatinga draught as required.

lMy improved chimney-holder is adapted to recive most of the 'ordinaryforms and sizes of chimneys new Ain use. i

It willb'e seen that the employmentof a burner, constructed as abovedescribed, admits ofthe holder, with the chimney thereon, beinginstantly removed, immediately after the flame is extinguished, or whenthe Wickl is lighted, as the perforated hand is constantly'kept quitecoolby-the current of air .passing through it from the outside', and theholder may be grasped bythe fingers without fear of burning. The holderand` chimney may also bereplaced in a convenient and expeditious manner,without requiring to be turned around tofany particularposition,theconstruction of thestationary cone, in connection with thatof the opening in the top ofthe holder, being. euchI as 'to cause theholder to be'centred at all times as soonas they are brought together. u

, What I claim `as my invention, `and desirehto secure by LettersPatent, is

A stationary cone, B, in combination with a perforated 'chimney-holder,E, all constructed and arranged substantiall;v as and for the purposeset forth.- l Y JOHN MAGEE.
